Should You Worry About U.S. Government Debt? Yes and No.

U.S. government debt poses almost no near-term default risk, but its long-term trajectory is unsustainable unless growth, inflation, or policy changes improve the outlook.

• Because the debt is denominated in dollars and the U.S. controls its currency, Summitry considers traditional default risk effectively zero.
• The Treasury market is worth roughly $32 trillion and remains the deepest and most liquid debt market, while euro-denominated government debt totals about $14 trillion but is fragmented among several issuers.
• Persistent deficit spending keeps adding to the debt, making the long-term path unhealthy even though it is not an immediate crisis; Summitry advises checking the situation again in 20 years.
• The trajectory could improve if GDP growth outpaces debt, potentially helped by AI-driven productivity gains, or if inflation reduces the debt's real value at the cost of purchasing power.
• A crisis-driven restructuring, like those experienced by Greece and Argentina, is viewed as near-zero probability in the near term and low probability over the long run.

Takeaway: Investors should monitor the sustainability of U.S. debt rather than fear an imminent default, while recognizing that the dollar's reserve-currency privilege is not permanent and the long-term outlook depends on productivity, inflation, or policy change.
